I realise that Vettori's numbers aren't great, but then neither are Afridi's. It's the fact that he plays for New Zealand, where any wicket taking pressure he creates is blown away at the other end. Also the only comparison there would be Shakib, who can also bat, and his figures are so good thanks to playing a terrible West Indies side. Not saying he's a bad player, that might be the one change, but he needs to prove himself a bit more first.
